I am a bit of a dilletante trumpet player,
@Marty. Having grown up playing guitar and having added piano in college, I started playing brass instruments when my oldest son was little - I'd take his French Horn lessons whenever he couldn't make them. I now teach teach a handful of cornet (for the smaller/younger ones) and trumpet lessons every week and a few French Horn as well.
What I really like about your article is your progression as explained here:
"My recommendation is to begin with the original ETK+ movements and template—it works. Then, once you understand the process, according to your training goals, adjust the movements to fit your needs while continuing to follow the structure and intent of the modules."
There's a lot of training wisdom condensed into those couple of sentences.
